The drawings illustrate a preferred embodiment of the invention. However, it isy to be understood that in adapting the same to meet Vdifferent conditionsvarious changes in the form proportion and minor details` of construction may be resorted to without'de! parting from the lnature of the invention as claimed hereinafter. 1

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

ln accordance with the present invention, the toy may have any configuration according to the machine or device of which it is representative. The toy contains within inself va motor of the helical or herringbone type and in addition holds a supply of motive medium which may be in the form of.

compressedv air. The body of the toy is hollow and constitutes a chamber or tank of moderate strength to hold air under low pressure, sufficient to operate the motor fora reasonable period. This same space may also receive the motor. However, it is essential that the motor exhausts into the open air and that the motive medium pass from the storage chamber into the motor by way of the pipe l2 thereof.

As indicated most clearly in Fig. 2 the motor comprises a pairfof rotors l which are provided upon their exterior with ribs or nights in spiral or herringbone forni. The casing inclosing the rotors is formed of two similar or like sections 2 which may be drop forged or constructed in any economical way, and which are secured by means of bolts 3 passing therethrough. The motor is relatively small and compact and the rotors may be solid as indicated in Fig.

3 or hollow as shown in Figs. ll and l2.Y

The latter construction is preferred because of the small amount of effort involved and the resultant lightness of structure which is desirable.

Fig l shows a train of cars embodying a. locomotive, a tender 5, and a car 6. These several'members may be of any 'cheap and light `construction and are adapted to be coupled vin any way. The motor designated by the letter A is disposed within the locomotive i and the drive shaft 7 thereof is provided with a worm 8 Vwhich is in mesh with a worm wheel 9 secured to the drive aXle of the locomotive.v A. tank l0 is disposed within the tender 5 and' car 6 and con-- tains compressed air. A flexible tube ll connects the tanks l0 and connects the tanks with a pipe l2 by means of which the motor medium is supplied to the motor. rlhe eX- haust from the motor passes off Vby way of a pipe 13. The exhaust maybe utilized in a lvariety of ways for operating ya signal or for assisting in the propulsion or control of the toy.

Fig. 5 and the detail views thereof show the means for coupling the parts of the train pipe 11, said coupling embodying 'similar members, each containing a valve 14, a spring 15 in cooperative relation with the valve for normally holding it seated and a stop 16 for limiting the movement of the springs and the valve in one direction. The stop 16 is of conical formation and Vhollow and forms a support for the spring 15 which iS of helical formation and tapering to correspond with the tapering end of the stop 16. Each member of the coupling comprises va shell 17 and an inner hollow member 18.

The two members are adapted to be connected by means of a bayonet joint 19, each member being provided with an element constituting` the joint.

Referring now in particular to Fig. 5 it -will be observed that the stop 16 serves not only as a support for spring 15 whose function is to insure the closing of the valve but the nozzle-like projection forms a stop for the valve allowing it to open just enough for the free passage of the air. Now, when the outer male sleeve of the coupling is inserted into the female sleeve until its edge just passes the bottom of the locking slot, there is established a continuous, non-leakable passage between the two adjoining air fluid compartments. The valves 14 are not yet open but their stems are in contact.

The further telescoping movement of the outer sleeve to the point of locking is di-V vided equally between the two valves by adjusting the length of the forward end of the stop first mentioned. This prevents either valve taking up all of the movement in case the other valve shouldstick, and also insures the positive and equal opening of both valves.

Fig. 8 illustrates' a toy boat 20 the hull of which constitutes a chamber to receive air under compression. A motor A of the type herein described is located within the hull of the boat, and the drive shaft 21 is provided at its rear end with a'propeller 22. The exhaust pipe 13 from the motor is arranged to discharge the spent motivev medium in the rear of the boat so as to act upon the propeller and materially assist in the operation thereof so as to propel the boat. In this case both the motive medium and the motor are containedwithin the hull of the boat, and the motive medium is admitted to the motor by means of a valve 23 which is controlled from the outside by means of a stem 24.

Fig. 10 illustrates the invention applied to a flying machine the body of which is indicated at 25 and is hollow to receive both the motor A and the motive medium. The drive shaft 26 of the motor is provided with a propeller 27. The exhaust is discharged downwardly and rearwardly by means of the pipe 13 and back of plane 28 so as to assist materially inf liftingl thev` machine from charged pled when it is required to Vsupply the tank Y or body of the toy with compressed air for operatingthe motor.

Having thus fully described my invention what I claim as new and desire to `secure byLetters Patent, is z- 1 1. A toy comprisingla hollow body adapted to contain fluid motive medium and a motor located within the body of the toy and adapted to be driven by the uid 'motive medium, the drive shaft of the motor being provided with a propelling element and the exhaust from the. motor being utilized for operating a signal. Y Y

2.l A toy embodying a hollowbody` adapted to contain fluid motive medium, a motor disposed within a body of thetoy and operable bythe fluid motive mediumY derived from the body of the toy, thedrive shaft of the motor extending beyond the body of the toy and provided v.with a propelling element and the exhaust from the motor discharging medium, a pipe connecting said tank with the4 motor anda coupling. in the length of the pipe and between units and comprising complemental members each containing a Valve, a hollow stop of conical form, a conical helical spring, and connecting'meansV for securing the members when properlyV assembled.

4. A toy comprising units lcoupled in train, a motor mounted upon one of said units, a tank containing fluid motive medium, a pipe connecting said tank withthe motor; and a coupling in the length of the pipe and located between the unit and com-Y prising a plurality of sections, each containing a valve, a stop, yieldable `means associated with said stop, and meansfor connecting and securing the members together when properly assembled.

In testimony whereof I in presence of two witnesses.v
